Customized Eclipse Installer [message #1801065]

Hi,

I am trying to update my customized Eclipse installer by using our mirrored copies of Eclipse update sites.

According to another topic (https://www.eclipse.org/forums/index.php/t/1080649/),
I mirrored http://download.eclipse.org/oomph/products/latest/repository
and http://download.eclipse.org/oomph/updates/latest

Then, i added
-Doomph.installer.update.url=file://......./download.eclipse.org/oomph/products/repository
-Doomph.update.url=file://......./download.eclipse.org/oomph/updates/latest
to the eclipse-inst.ini, and it worked.

My question is, what are the differences between these two repositories? because I found that if I only use 'Doomph.installer.update.url', it also worked. Do I still need to keep 'Doomph.update.url'?

Thank you,
Dongcheng

The product site (installer.update) is for updating the installer itself. This site is checked on a background thread when the installer launches, and if there are new versions of any of the installer's bundles and features at that site, the installer will display status indicating that updates are available.

Hi Ed,

Thanks for replying, your explanation of 'installer.update.url' is very clear. Could you please also talk about the other one 'update.url', what does that site is for?

Thanks,
Dongcheng

For example, in the generated product catalog, org.eclipse.products.setup, there is this task:

<?xml version="1.0" encoding="UTF-8"?>
<setup.p2:P2Task
    xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:setup.p2="http://www.eclipse.org/oomph/setup/p2/1.0">
  <requirement
      name="org.eclipse.oomph.setup.feature.group"/>
  <repository
      url="${oomph.update.url}"/>
</setup.p2:P2Task>

Also the *.ecore models have annotations like this:

<?xml version="1.0" encoding="UTF-8"?>
<setup.p2:P2Task
    xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:setup.p2="http://www.eclipse.org/oomph/setup/p2/1.0">
  <requirement
      name="org.eclipse.oomph.setup.feature.group"/>
  <repository
      url="${oomph.update.url}"/>
</setup.p2:P2Task>

These things ensure that an update site for any of Oomph's setup technology is available when creating the installations with the installer, and of course specifies where this update site is located.

Hi Ed, thanks for the clarification. When and how are new plugins updated from this update site for any of Oomph's setup technology?

Also, there is an ini task to add the oomph.update.url to the Eclipse installation, does that mean that Eclipse would update something when new plugins appeared in the update site? When would this take place? When eclipse started?

It seems one question just begs for the next...

Plugins are updated by when you perform p2 tasks of course. Whether that pulls updates for "Oomph bundles" from "this site" depends on whether there is a p2 task for "this site" with requirements for "Oomph bundles"; the generated product catalog has both such a requirement (the setup feature) and a use of this site variable.

No, what Eclipse itself does depends on what update sites are available in the preferences.
